SPECIFICATION forming part of Letters Patent No. 615,946, dated December13, 1898.

Application filed November 9,1896. Serial No. 611,552. (No model.)

To all whom it may concern.-

Be it known that I, STANISLAV ZUNGEL, a subject of the Austrian'Emperor,and a resident of Prague, in the Kingdom of Bohemia, Austria-Hungary,have invented'certain new and useful Improvements in Velocipedes, ofwhich the following is a specification.

Myinvention relates to a velocipede which can be driven by the hands aswell as by the feet of the rider. In consequence of the peculiarconstruction of the frame and of the connection of the crank and pedalwith a suitable connecting or guide rod the machine can be much morereadily and conveniently driven up hill than heretofore.

In the accompanying drawings, Figure 1 is a side view, and Fig. 2 aplan, ofa bicycle constructed according to myinvention. Figs. 3 and 4are a side and an end view, respectively, of the gear for driving themachine by hand, together with. the connecting or guide rod. Figs. 5 and6 are an end and a side view, respectively, of the driving rod andwheel. Figs. 7 and 8 are a side and an end view, respectively, of theguide-rod joint. Figs. 9 and 10 are a side and an end View,respectively, of the rear fork and wheel. Figs. 11 and 12 are a side andan end view, respectively, of the driving-gear. Fig. 13 is another sideView of the rear fork and wheel. Fig. 1 1 is a longitudinal section ofthe air-pump. Figs. 15 and 16 show the rear wheel and fork in frontview. Figs. 17 and 18 show in side view the connection of the rearwheeland fork with the guide-rod. Fig. 19 is a longitudinal section ofthis guide-rod. Figs. 20 and 21 show a plan of the guide-rod. Figs. 22,23, and 24 are respectively a side and a front View and a plan of thesaid guide-rod.

The bicycle-frame consists ofthe guiderod d, the rear-wheel-fork pillara, the saddle-bar e, and the connecting-rods ff and g g. The rods 9 gare fixed to the saddle-bar and are provided below with the bearingst t.In the bearings t 25 are mounted the gear- Wheels 1' z". The rods g gare also fixed to these bearings and are furnished above the hub withthe openings q q, wherein rests the axle of the front wheel. The rearwheel is supported by the fork 12 of the rod, which is firmly fixed tothe pillar a, the latter being free to turn within the sleeves e f Theguide-rod d riveted to the arms 10 10.

is niovably held in the headc of the fork of the front wheel h and inthe sleeve 13, secured to the saddle-bar c. This guide-rod is furnishedwith transverse arms 8 8, Figs. 19 and 20, which are connected by thetie-rods Z Z with the npperarms 5 5' of the pillar a. The tie-rods Z Zmay be connected parallelly or crosswise. The rod d is furnished abovewith a crosstube 9, upon which can turn the sleeves 16 and 17, Fig. 2.The hand-levers b b are rigidly connected to the sleeves 16 and 17 whichare provided with the short arms 10 and 10. The supports 18, which arefurnished with ball-and-socket joints at their extremities, are

The joint is secured to the ball carried by the upper end of the rod 0.at their lower extremities to the rods 14 and 14: by the joints '0 and0, these joints enabling the rod 0 to be turned in every direction,whichis absolutely indispensable in driving the machine. The guide-rods 14:and 14 are supported by the bearings m m, fixed to the rods 01 diand aredirectly connected by means of the cross-heads 19. and 19 with thecross-head rods 15 and 15, which are carried by the tubular projections19 p of the gearwheels t' 2". The gear-wheels i t" are furnished withthe pedalsjj and are coupled by means of teeth or of chains with thewheels 5 s,

mounted on the axle of the wheel h.

The rod a, which is the pillar of the rear fork and is free to turnwithin the sleeves e f contains an air-pump 4, with a piston 2 and apiston-rod 1, provided at the top with a knob or handle ,2. Below is asmall tube 3, to be connected to the usual air-valve 7 by the aid of asmall india-rubber pipe 6, so that the inflation may be carried on inthe ordinary manner by the aid of the air-pump 1.

Oneof the forks l2 and 12 is provided with the valves 0 r and its cavitycan be filled with oil. The saddle 70, carried by the bar e, is longerthan usual and may be inflated with air. The wheels it" are rotated bypedaling, being connected, by the cranks 15 15, the guide-rods 14 14:,and the tie-rods c c, with the lovers b b, acting also as guides, so asto be able to rotate the gear-wheels it" when driving by hand as wellas. by the feet. As shown, the guide-rod is directly connected with therear wheel h, and hence the direc- The tie-rods c and c are connectedtion of the wheel can be regulated by the same.

With this construction of bicycle the pedalcrank shaft is revolved bythe rider in a direction opposite to that which is usual in bicycles. Inthis'bicycle the steering is performed by the swiveling of the backwheel through the levers 8 8 and 5 5, which bare a proportion to oneanother of two to one or four to one and act on each other by the director crossed rodsl Z. The driving is performed partly by hand-lever gear b16 l0 and b 17 10 and draw-rods c 14: 15 and 0'1415', actingondriving-wheels z' z", symmetrically placed on both sides of thewheel-axle s, and on the axles of which are also the pedal-cranksjj, sothat hand and foot driving may both be used for driving the wheel h bydirect gear or through a chain and the center of gravity of the systemmay always be brought into a vertical line with the driving-Wheels 71 2'through the elongation of the saddle K, permitting of the backward orforward displacement of the rider, thuspermitting easy ascent ofinclines, more perfect braking and turning in smaller curves than isusual.

I claim as my invention In a cycle, a frame comprising fixed forksconverging on the axis of the pedal-cranks whereof the leading fork g israked forwardly of said axis, the said frame having at the commontermination of said fixed forks bearings for two crank-shaftsrespectively and above the latter,an axle for the leading-wheel, at itsrear a steering-socket and aframe-tube 6 extending from the head of thesteeringsocket to the head of the fixed fork g the for- Ward portion ofwhich frame-tube e is downwardly curved, in combination with asteering-fork 12 with pillar adapted to be rotarily movable in saidsteering-socket, a leadingwheel h journaled to revolve on the aforesaidaxle in said frame, a rotary guiding-pillar d in said frame at itsforward end in extension of said fork g, a cross-head 9 to said pillar(Z, arms on said pillars a and cl, rods Z connecting said arms,hand-levers b, b, pivoted on said cross-head 9 and extending rearwardly,forward extensions 10, 10 to said levers b 1), wheels 1' 1" adapted togear with pinions on said leading-wheel 7t pedal-cranks on the axles ofwheels t t" rotary pedals on said cranks, eccentrically-placedWrist-pins on the wheels 71 '5', universally-jointed rods connectingsaid extensions 10, 10' to said wrist-pins and adapted to permit of alateral oscillatory movement of levers b b for purpose of steering, andvertical reciprocating movement thereof for assistance in the rotationof the wheels it, and a saddle of equal breadth throughout and curved inlateral elevation and extended in the plane of the frame above thecurved part of frame-tube c to enable the cyclist to assume positions inwhich his center of gravity bears the same relation to the drivingcenter, under different inclinations of road, the Whole substantially asset forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
